The problem was dealt with using the method of Vollkenshteyn et al. (Ref.6) and blayants (Ref.?), using an ethane-like model D for the disilane molecule. The equilibrium 3d'lengths of bonds were taken to be 23.2 and 1.48 X for Si-..,i and Si-H respectively. It was assiimed that all angles were tetrahedral.

This mixture was denoted by the formula F3 B.11HiD kwhere i and k may have the values 0, 1, 2, 3 and i + k 3 . The sDectra were recoraed usinS a spectrometer IKS-11 in the region from 2.5 to 15 IL . To avoid absorption by atmospheric water vapour and carbon dioxide, nitrogen was passed through the spectrometer.

The force fields, frequencies and forms of normal vibrations were calculated using the method of Card Vollkenshteyn, Yellyashevich, Stepanov (Ref 4) and 1/2 Mayants (Ref 5).

When using these coefficien~,'~s for calculating the oscillations, results are obtained, which show good agreement with experimental observations. The following conclusions are drawni 1) When changing from tetramethyl- silane to methylahlorosilane, the coefficients (Q,11~, ) decrease systematically, which is related with the extension of the distance Si-C. If one of the methyl groups is replaced by a chlorine atom. the jump is particularly large. A spectrum analysis shows an increase of the frequency of natural stretching vibrations. This is connected with the intensification of the covalent character of the bonds. 2) When the chlorine atoms are surrounded bLT silicon, a slight but systematic decrease of the coefficients is observed, which is related with the change in the length of the bond C - H- 3) The reciprocal bond Si-Cl leads to an increase of its strength. 4) The strength of the inner and outer angles of the CH 3 group is somewhat diminished.

PATHOGENESIS AND PRINCIPLES OF TREATMENT OF RADIATION CATARACTS (EXPERIMENTAL INVEZTIGATION) (Russian text) Kovalev 1. F. - OFTALM.ZH. 1956, 5 (271-278) Experimenrs -werE -carried out on 192 rabbits (350 eyes) irradiated with roentgen rays in doses of 600-3000 r. , with an observation time of up to 2 years. Histologic examinations were made on 78 crystalline lenses, Including 11 lenses from control (unirradiated) eyes. Development of cataract was studied by biomicroscopic and histomorpbologic methods. Biomicroscopical examination revealee- the appearance in the irradiated eye of irregular delicate radial, granular or noccular opacities on thtt anterior surface of the lens just beneath the anterior capsule. All 3 types of opacification developed within 3-4 months after the irradiation. llistornorphologic examination revealed pictures of damage.to the normal structure which varied with the development of the process and of its course. The author believes that the immediate cause of cellular death following an ionizing radiation Is not theradiat- ton damage to the cells but changes in the conditions of the medium to which normal cells must adapt by means of morphologic and functional reconstruction. Resulting from the specific action of Ionizing Irradiation the regular differentiation process of the epithelial cells of the ienticular equatorial zone is disturbed both in the direction of formation of epithelium and of formation of lenticutar fibres. It was found that after large single dos,~s (more than 1500 roentgens) a suppression of barrier and trophic functions of t~e anterior and posterior capsular epithelium came to the foreground, The disturbances of the differentiation process of the lenticular epi- theUum ate yegfirded as a basic link In the mechanism of the development of Irra- diation cataract. The solution of the problem of a rational treatment of the lenti- cular radiation damage (also of radiation damage to other tissue) must proceed -along the lines of study of the factors which would stimt late the adaptive function and the differentiation process of the cells, (S) 6 Vq t_,t~ Y, `The Specific Nature of the Biological Action of Ionizing Radi- a+.i on, " b, A .1 1.

(2) By using larger doses there was a decrease or loss of the function of multiplica- tion and motion in addition to decreased adaptation, but the disturbance of conjugation and motion was easily reversible and was not transmitted to subsequent generations. (3) The third stage is characterized by the irreversible loss of the function of adaptation, reproduction, and motion and death under rays. KO VA L IZ7 V/ I F The author concludes that injuries appearing in the first stage and due to small doses are specific and are expressed in the decreased func- tion of adaptation while all the other vital functions remain intact. The biological action of ionizing radiation in the second and third stages, however, are nonspecific and are expressed in a general denaturation of important enzyme and protein complexes. The comparative relationship bet,een intensity of ionizing radiation to specific and nonspecific injuries are: with the increase of done there is an appropriate increase of intensity of nonnpecifio gem2ral-denaturation aymptonq, but increasing the dose has very little effect on the specific effect. 6 KOVALEV. 1.F., atarshiv nauchny7 sotrudnik ritique of certain baslo concepts in radiobiology.

A few heats of the alloy were prepared for the investi-a- tion in a steel crucible (12 kg) with the application O.L flux V12. Magnesium and alloying addition MGS-1 was melted at 1700 to 7200C. Thorium was introduced in the form of turnings at 8000C in a preheated bell. During the introduction of thorium, the surface of the metal bath was covered with a small amount of flux containing 55016 of KC11) 28% of CaC12, 1W0 Of BaC12 and 2% of CaF2. The alloy (cooled to about 720 to 7400C) was cast into metal moulds, reheated to 100 to 1500C.

The pattern of this deflection is determined by an analysis of the forces acting on,the arc-discharge plasma. In this connection the authors present the results of an experimental investigation performed to verify the theory that the model of a flexible conductor with current applies to this are. A homogeneous magnetic field was created by means of coils. The relationship between the intensity of.the transverse magnetic field N, the arc length and the current intensity I a determined by means of a device consisting wa of electrode 1 and fixed anodes 2 and 3 isolated from one another and connect6ed in~ parallel to the circuit of the are current (see Fig.~l of the Enclosure), on fixing Cu) are burning in at e.g. 60* the angle of deflection of a DC direct-polarity (W- g in 1/3 r ..1 3272-66 J ACC NRe AP50215606 argon (tungsten electrode) within the traneverse.magnetic field.

It is shown that this re- striction may be to a large a' i- xtent-,elim nated by stabilizing the are by means of the flow of the protective gas. This results in equalizing the plasma velocity field and increasing the total velocity,of the cathode flow and thus in deforming the are as a single whole, particularly in theupper (near-cathode) region of the column. Another method of stabilizing the are is the employment of the so-called "directing wall". In this case, the arc diechargemoving in a commercial-frequency transverse.. magnetic field is bounded by two graphite or cooled copper blocks (see Fig. 1 of the Enclosure). A tungsten electrode tind the protective gas are passed through the space between the blocks. The flow rate of the argon is 7-8 liters/min, which precludes Card 1/3 KOVALEV, I.M., inzh.

Hence, the melting power of the compressed are may be maximized when the welding rate is-zero, i.e. during arc spot welding. This has the disadvantage of leading to a rapid increase in the extent of the molten layer underneath the arc, since the overall amount of the molten electrode metal and molten base metal in- creases proportionately in time. This, however, can be remedied by adjusting the pressure exerted by the San jet on the weld pool. Fig. 1 presents the flow rate VC02 L 3581-)4-66 ACC NR.

It is shown that spet-troscopic identification of the derivati'ves of M and y pyrone by means of the frequencies and intensities of the absorption bands of the hydro)WI, carboxWl, and other groups is possible. The chelate hydrogen bond of the flavonoids, vbich plays an important role in the manifestation of their biological action, is investigated. Work is done on the preparation of a chart of Ir spectra of the derivatives of a. and y pyrone (standardization of the measurement of the spectrum, development of type of documentation).

An exact analytical determi*nation of the capacitance of a strip line presents considerable difficulties since it depends on the solution of 'elliptical integrals of the first order. The capacitance of such a symmoirical line was therafore determined experiment ally, the mcasurembntj3 being conducted at a frequency of 60 Mc/s by means of a*Q-meter. 'It is found from the experimental data that the capacitance can be approximately described by the following fomaula: C = 0.15 1 + d j OM whereb is the width of the central strip of theAine and Card 1/3 s/14-1/62/005/Oo4/009/010 Determination of the ....
